RCF SUB 905-AS MK3

The RCF SUB 905-AS MK3 stands out as a self-powered subwoofer designed for extended low-frequency performance, featuring internal DSP. Housed in a compact cabinet, it incorporates a cutting-edge 15" transducer with ceramic magnets and a 3.0” voice coil. The internal amplifier handles up to 2200W power output, achieving sound pressure levels of up to 133 dB. Proprietary Bass Motion Control processing ensures extended linearity and exceptional sound integrity. Rear panel controls offer presets, crossover frequency, polarity selection, cardioid, and output delay settings. The rugged, tour-ready, all-wood cabinet, with a scratch-resistant polyurea coating, is stackable and lightweight, facilitating quick setups and tear-downs. Specifically crafted for demanding applications, the SUB 905-AS MK3 serves as the ideal workhorse for music professionals.

RCF subwoofers are the preferred choice of sound engineers due to their high SPL levels at very low frequencies, compact dimensions, self-powered design, internal delay control, long-term reliability, cardioid configuration options, and an impressive size/weight to SPL output ratio. In both live sound and DJing applications, the SUB 905-AS MK3 ensures an engaging and immersive experience for the audience.

Renowned for their lightweight yet powerful performance, RCF woofers set the industry standard. Precision Transducers engineers have developed specific magnet sizes and moulds to optimise magnetic flux while minimising weight. The 15", 3.0" voice coil magnetic circuit topology delivers high performance in three key areas: maintaining a consistent, high-integrity magnetic flux gap, exceptionally low distortion, and efficient integration of the magnetic circuit in a lightweight design. The T-pole design optimisation minimises flux modulation during typical voice coil movement.

The SUB 905-AS MK3 boasts the most powerful amplifier in its class, with 2200W power output. RCF's advancements in transducer design result in stronger and more powerful woofers, complemented by an amplifier that manages extreme sound pressure levels with an ultra-fast attack, realistic transient response, and minimal heat loss. The energy-efficient design eliminates the need for a cooling fan, and the stereo input circuit with crossover features a low distortion design and advanced safety limiter to preserve the true character of the input signal at all levels.

Built for the rigors of touring and live performances, RCF cabinets feature high-quality multi-ply hardwood construction with a black polyurea finish. Stackable and lightweight, they facilitate easy setup and tear down, with ergonomic handles for comfortable transport. A pole receptacle on the top and side allows versatile configurations, and the powder-coated front grille includes a transparent-to-sound foam backing for protection against dust. The SUB 905-AS MK3 is a tour-ready workhorse, combining durability and reliability for diverse performance situations.
